82 PACIFIC COAST AVIFAUNA No. 14 



tiuental divide. There are only a few records. One taken at "Silver, Mis.soula 

 County," June 25, 1S91, by ('. P. Streator (Bendire, 1895, p. 183;. At present 

 the only place in the state named Silver is in Lewis and Clark County, north of 

 Helena. If this was formerly in Missoula County, and is the locality referred to, 

 it is especially interesting because east of the divide. One seen at Yellow Bay. 

 Flathead Lake, August 25. 1914. Swifts were also seen at Somers by H. P. 

 Stanford (Saunders, 1915b, p. 111). I noted this species again, in the same 

 place July 25, 1915. Other records are : Missoula, July 25, 1915, and Seeley 

 Lake, August 20, 1915 (Kittredge, MS) ; South Fork of Flathead River (Betts, 

 1916, p. 162), identification questionable; Kalispell, i\lay 30, 1916, and Wood's 

 Bay, Flathead Lake, August 12, 1916 (Sloanaker, MS) ; seen at JIany Glacier 

 Hotel, Glacier Park, in midsummer (F. M. Bailey, 1918, p. 58). 



165. Aeronautes melanoleucus (Baird) 



WniTE-THKd.VTEn SwiFT 



A very rare or local summer resident, occurring in scattered localities over 

 the state, though the ma.iority of records are in the eastern half. Seen June 22, 

 1860, between Forts Union and Benton (Cooper, 1869b, p. 296) ; Belt River Can- 

 yon, feeding young in crevices of the rock in July, 1881 (Williams, 1882c, p. 

 122) ; seen by Bowman on the Powder River (Camei-on, 1907, p. 390) ; Billings, 

 August 12, 1900, and between Billings and Miles City, August 13, 1900 (Jone.-, 

 and Dawson, 1900, p. 32) ; six seen at Corvallis, Bitterroot Valley, May 19, 1911, 

 two, .May 27, 1911, and two, May 22, 1912 (Bailey, ilS). At least twelve colo- 

 nies of these birds nest in the vicinity of Billings, in rim-rocks. A set of two 

 eggs was taken thirty miles below Billings on the Yellowstone, June 17, 1918. 

 The set was evidently complete, as the two eggs had remained in the nest several 

 days without an additional egg being added (Thomas, MS). 



166. Archilochus alexandri (15ourcier & Mulsant) 



Black-chinned Hummingbird 

 A rare summer resident of extreme northwestern I\Iontana, west of the con- 

 tinental (livid.'. Taken at Columbia Falls, May 27, 1893, by Williams (Bendire, 

 1895, p. 199) : two males seen at Stevensville, May 28, 1912 (Bailey, MS) ; seen 

 at Yellow Bay, Flathead Lake (Silloway, from an unpublished manuscript) ; 

 seen at Jlissoula, June 6 and July 17 (Kittredge, MS). These constitute tiw 

 only records. 



.167. Selasphorus platycercus (Swainson) 



Broad-tailed Hummingbird 

 But two definite records of this species. One taken by Lieutenant Colonel 

 Wirt Robinson in 1907 at Chico, Park County, according to information sent me 

 by Mr. M. P. Skinner. One taken at Upper St. Mary's Lake, Glacier National 

 Park in 1895 by Bailey and Howell (F. M. Bailey, 191S, p. 58). This bird, how- 

 ever, ma.y be common in the southern part of the state, ily record of the nesting 

 of this sjieeies in Gallatin County must remain doubtful (19091), p. 197, and
